The current International Artwork (IA) badge is one of the (if not the) biggest way of measuring cards success. It's currently based on the congregate market value (MV) of a nation's card collection. By doing this, the stat encourages nations to hoard cards that have little resale value but high MV in their collections. However, because of cards inflation, most of these cards have resale values that are mere fractions of the "Estimated Market Value", thus making the MV a poor measure of a card's true value. This also is highly unrealistic, as no one in a real economy would care about an "estimated value" if it had minimal effect how much they'd actually get out of it. These cards also serve as a bank hole for new players who hold the notion that an "estimated market value" actually represents how the market values a card, and thus its eventual resale value.
Instead, we can base IA off of a nation's available bank. By forcing nations to liquidate cards to increase the stat, it'll discourage overly inflated "Market Values", and move players towards trading cards that have higher re-sale value, more in line with a real-world economy. This will be able reduce the effectiveness of over-inflation, and bring the MV of cards to more realistic values that actually represent a card's value.
